I was wondering if anyone could shed some light on this input lag issue with the PVP.net client. I stopped playing this game for a month because of class, and decided to jump on and play a game. However, I'm getting insane amounts of input lag. Whether it be trying to type something to a friend, to selecting a champion. Everything is happening a few seconds after I do it. I did not have problems like this before, and nothing about my computer has changed.

In game, there are no problems. Is anyone else experiencing these issues?

There was a discussion about this with lima beans here a few days ago, those of us who were on at the time gave as many details as we could.
